Hello, sorry to sound so stupid, but just got my F1 ecig today and have no idea how to fill these clearomizers. I have looked at youtube vids but there are so many different ones and none of them look like mine. They are enclosed in the pen-like e-cig with metal hole on one side and the plastic hole on the other. I tried filling one first with syringe from juice bottle into the metal end and then it all came leaking out, so wiped it off and tried the other end. DUH! its a 510 Ego pen type Riva if that helps. Thank you ever so much. really want to try this out properly now.
